About machines for which SF4D-□-01 is used

  • When using SF4D-□-01 as a safety device for a press or shearing machine (paper cutting machine) in Japan, make sure that the press or shearing machine (paper cutting machine) satisfies the following specification requirements. Do not use SF4D-□-01 if the machine does not meet the specification requirements.

Press machine

Item Specifications
Machine type Press equipped with immediate stopping mechanism and restart prevention mechanism
Pressing capacity 50,000 kN or less
Immediate stopping time 500 ms or less
Stroke length Within (Protective height – Die height)
Die size Within bolster width

Others

  • This device has been developed / produced for industrial use only.
  • Do not use during the initial transient time (2 sec.) after the power supply is switched on.
  • Avoid dust, dirt and steam.
  • Take care that the safety light curtain does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
  • Take care that the safety light curtain is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.

Communication module

  • The use of the communication module, SF4D‑TM1 (optional), enables setting of various functions of the device.
    (Note that settings cannot be changed when SF4D-□-01 is used.)
    Details related to the safety distance, such as the minimum size of detectable objects, varies for some of the functions. When making individual settings, calculate the safety distance and provide a space greater than the safety distance when setting up the device. Unless a sufficient space is provided, the machine will not stop before the dangerous parts of the machine is touched and death or serious injury can occur.
For the details of function settings made using the SF4D-TM1 communication module (optional), see the manual for the communication module.

Corner mirror

  • The corner mirror has not received type examination by the Ministry of Health, Labour and Welfare; therefore, it cannot be used for presses or shearing machines (paper cutting machines) in Japan.
  • Be sure to carry out maintenance while referring to the instruction manual for the safety light curtain SF4D series.
  • Do not use if dirt, water, or oil, etc. is attached to the reflective surface of this product. Appropriate sensing range may not be maintained due to diffusion or refraction.
  • Make sure that you have read the instruction manual for the corner mirror thoroughly before setting up the corner mirrors and safety light curtains, and follow the instructions given. If the equipment is not set up correctly as stipulated in the instruction manual, incident light errors may result in unexpected situations which may result in serious injury or death.
  • Please download the instruction manuals from our website.
  • Safety light curtain SF4D series cannot be used as a retroreflective type. Avoid installing the safety light curtain as a retroreflective type when this product is applied.
  • The mirror part of this product is made of glass. Note that if it is broken, the glass shards may fly apart.
  • Do not use if crack or breakage appears on the reflective surface of this product. Proper sensing range may not be maintained due to diffusion or refraction. If crack or breakage appears on the reflective surface of this product, replace the product.
  • When adjusting beam channels with a laser alignment tool, etc., take sufficient care that the laser beam reflected by this product does not enter the eyes.
  • Failure to follow the above items may result in death or serious injury.

IO-Link communication unit

  • Do not use the IO-Link data for safety control.
  • This product cannot be used to directly enter settings from the IO-Link master unit to a safety light curtain using IO-Link communication.
  • Safety light curtain setting information copy function is a function assuming maintenance of safety light curtain. Please use only when writing the safety light curtain before replacement to the light curtain after replacement. If you write to non-replacement parts, it may not operate properly.

Sensing area

  • Make sure to install this product such that any part of the human body must pass through its sensing area in order to reach the dangerous parts of the machinery. If the human body is not detected, there is a danger of serious injury or death.
  • Do not use any reflective type or retroreflective type arrangement.
  • Multiple receivers (emitters) cannot be connected for use with a single emitter (receiver).

Safety distance

  • Calculate the safety distance correctly, and always maintain a distance which is equal to or greater than the safety distance, between the sensing area of this safety light curtain and the dangerous parts of the machinery.
    (Please check the latest standards for the equation.) If the safety distance is miscalculated or if sufficient distance is not maintained, there is a danger of serious injury or death.
  • Before designing the system, refer to the relevant standards of the region where this device is to be used and then install this device.

Safety distance

  • The sizes of the minimum sensing objects for this device vary depending on whether or not the floating blanking function is being used.
    Calculate the safety distance with the proper size of the minimum sensing object and appropriate equation.

    Note: When SF4D-□-01 is used, the floating blanking function cannot be used.
  • The safety distance is calculated using the equations given on the following pages when a person moves perpendicularly (normal intrusion) into the sensing area of the device.
    If the intrusion direction is not perpendicular, always check the related standards (regional, machine standards, etc.)
For use based on EN ISO 13855 / ISO 13855 / JIS B 9715

For intrusion perpendicular to the sensing area
<When the minimum sensing object is ø40 mm ø1.575 in or less>

• Equation (1) S = K × T + C

S: Safety distance (mm)
Minimum required distance between the sensing area plane and the dangerous part of the machine
K: Intrusion speed of person or object (mm/sec.)
Normally 2,000 (mm/sec.) is used.
T: Response time of overall system
T = Tm + TSF4D
Tm: Maximum response time of machine (sec.)
TSF4D: Response time of device (sec.)
C: Additional distance calculated from the minimum sensing object of the device (mm)
The value of C cannot be less than 0.
C = 8 × (d − 14)
d: Diameter of minimum sensing object (mm)
When calculating the safety distance S, the following five cases must be considered. First calculate using K = 2,000 (mm/sec.) in the above equation. Consider these three cases for the result: 1) S < 100, 2) 100 ≤ S ≤ 500, and 3) S > 500. If the result of the calculation is 3) S > 500, calculate again using K = 1,600 (mm/sec.).
Consider these two cases for the result: 4) S ≤500 and 5) S > 500.
For details, refer to the manual.
When the device is used in "PSDI mode", an appropriate safety distance S must be calculated. For details, refer to the standards and regulations that apply in your region or country.

<When the minimum sensing object is greater than ø40 mm ø1.575 in>

• Equation S = K × T + C

S: Safety distance (mm)
Minimum required distance between the sensing area plane and the nearest dangerous part of the machine
K: Intrusion speed of person or object (mm/sec.)
Normally 1,600 (mm/sec.) is used.
T: Overall response time of system
T = Tm + TSF4D
Tm: Maximum response time of machine (sec.)
TSF4D: Response time of device (sec.)
C: Additional distance calculated from the minimum sensing object of the device (mm)
C = 850 (mm) (Constant)
